PIPE 'JORNEGTION FOB GAS-METERS.

Specification ofLetters Patent.

Patented March 2, 1909.

Application filed May 4, 1903. Serial No. 236,672.

To all whom it may concern:

Be it known that I, ADAM EHEBALD, a citizen of the United States ofAmerica, residi at New York, in the borough of the Bronx, county andState of New York, have invented certain new and useful improvements inPipe Connections for Gas-Meters, of which the following is aspecification.

This invention relates to an improved pip econnection for gasaneters.

The gas-meters in general use are provided at one side with a gasinletpipe and at the opposite side with an outlet-pipe, to the upper ends ofwhich a threaded union is applied by which the connection is made withthe supply-pipe from the street-rnain and with the service-pipe for thebuilding.

in making the connection of the main and service-pipes with the inletand outlet pipes of the gasaneters, the unions at the upper ends ofthese pipes are frequently loosened and wrenched oil so that the pipesleak at these points of connection and require irequent repairs, whichnot only involves considerable expense but also great annoyance to thegas companies.

The object of this invention is to furnish an improved pipe-connectionfor gas-meters by which leakage due to the loosening of the unions atthe ends of the inlet and outlet pipe of the gasaneters is obviated anda reliable connection with the main and service pipes obtained, while incase of repairs, the unions can be easily detached and new unions or newoutlet or inlet-pipes substituted, as

required; and for this purpose the invention consists of apipe-connection for gasuneters which comprises an inlet or outlet-pipehaving a threaded union having a longitudinallyslitted nipple connectedwith the upper end of the inlet or outlet-pipe, the upper end of theinlet or outlet-pipe being wrapped around the nipple and provided withinwardly-bent lugs that are inserted through. the slit of the nipple forlocking the union firmly in the inlet or outlet-pipe.

The invention consists further in providing the union below its threadedportion with an undercut into which the upper edge of the outlet orinlet pipe is inserted and soldered so as to prevent leakage at thatpoint.

The invention consists lastly of a soldered anchor between the nipple oithe union and the inlet or outlet pipe, at a point opposite to the slit,said anchor forming an additional locking connection between the nippleof the union and the inlet or outlet-pipe, as will be fully describedhereinafter and finallypointed out in the claims.

in the accompanying drawings, Figure 1 represents a side-elevation of agas-meter of the ordinary construction with my improvedpipe-connections, Fig. 2 is a side-elevation of one of thepipe-connections drawn on a larger scale, Fig. 3 is a vertical centralsection through the pipe-connection on line 3, 3, Fig. 2, Fig. 4 ishorizontal section on line 4, d, Fig. 2, and Fig. 5 represents a blankfor the inlet or outlet-pipe of the gas-meter.

Similar letters of reference indicate corresponding parts.

teferring to the drawings, a represents a gas-meter of the ordinarywell-known construction. The gas-meter is provided at one side with aninlet pipe 0 and at the opposite side with an outlet-pipe d. To theupper ends of the inlet and outletpipes are applied unions i) and dwiich unions are respectively connected with the street niain thatsupplies the from the street in the usual manner, and with theservice-pipe for the building. The unions 5 d are each provided with athreaded upper portion and a smooth nipple 6 (Z below the same, thenippie being provided at one point of the circumference withlongitudinal slit 3 into which are inserted inwardly-bent lugs 5 (1formed at the upper ends of the inlet or outlet-pipes. The inlet andoutlet-pipes are made of sheet metal, preferably tin, of the blank shownin Fig. 5, the upper ends being made wider in such a manner that theylap around the nipples of the unions bBcZ while the lugs at their endsare inserted side by side into the slits s of the same and bent inopposite directions. The upper ends of the inlet and outlet-pipes arethen soldered to the nipples oi the unions so that a firm lookingconnection is obtained. By the inwardlybent lugs the union is preventedfrom getting loose and being turned in either direction when screwingthe main and servicepipes on the threaded unions, so that in this Waythe resulting leakage at these points is prevented, and thereby the lossof gas and expense for repairs obviated.

To render the connection of the upper ends of the inlet and outlet-pipeswith the unions still more intimate, the lower edge of the threadedunions 5 d is undercut at e, as shown in Fig. 3, so that the upper edgee of the inlet or outlet-pipe projects into said undercut e. WVhen thesolder is placed in the undercut 6 over the edge e, an absolutely tightconnection between the unions and inlet and outlet-pipes is obtained. Tostill more increase the locking connection between the union and theinlet and outlet pipes, the nipple of each union is provided with adepression 0 an d the upper portion of the inlet or outlet-pipe with ahole 0 through which solder is passed, so that a soldered anchorf with awiped head is formed, preferably at a point diametrically opposite theslit 8 in the nipple at the outside of the upper end of the inlet oroutlet-pipe, whereby an auxiliary means oi resisting any turning strainon the union when applying or removing the main or service-pipe isobtained.

The improved construction of the pipe con nection between the gas-meterand the main and service-pipes of the same obviates the objections tothe ordinary connections lieretofore in use, in which the unions becameloose and produced thereby leaky joints and expensive and annoyingrepairs. These are entirely avoided by my improved pipe-connection. Inthis way not only labor, time and expense is saved, but the annoyance ofsuch leaksand repairs to the gas users dispensed with.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent:

1. In a pipe-connection for gas-meters, the combination of a unionhaving a slit, and a pipe having lugs entering said slit side by sideand locked therein;

2. In a pipe-connection for gas-meters, the combination of a unionhaving a longitudinal slit, and a pipe around the nipple having lugsentering said slit from the outside and bent in opposite directions.

3. A pipe-connection for gas-meters, com prising a pipe formed of ablank having lugs at the meeting edges, and a union having a nipple witha slit in which said lugs are locked.

V l l l l l l l l 1 l 4. In a pipe-connection for gas-meters, thecombination of a union having a longitudinal slit, and a pipe formed ofa blank having a widened end wrapped about the union and having terminallugs inserted side by side through said slit and bent in oppositedirections.

5. In a pipe-connection for gas-meters, the combination of a unionprovided with a threaded upper portion and a smooth nipple below thesame, said nipple being provided with a longitudii'ial slit, and a pipeformed of a blank wr pped around the nipple and connected at the meetingedges inwardly bent lugs with the slitted portion of the nipple.

6. In a pipe-connection for gas-meters, the combination of an inlet oroutlet-pipe, a union provided with a threaded upper portion, andundercut at its lower edge and a smooth nipple, the nipple beingprovided with a longitudinal slit at one point of its circumference, theupper edge of the inlet or outlet pipe being wrapped around the nippleand provided. with lugs inserted into the slit of the same, while theupper edge of the nipple is inserted into and soldered in the undercutof the union.

7. A pipe-connection for gas-meters comprising an inlet or outlet pipe,a union having a smooth nipple, and a slit in said nipple, the upper endof the inlet or outlet-pipe being wrapped around the nipple andconnected. by inwardly-bent lugs with the slitted portion of the nipple,and a soldered anchor located at a point approximately opposite to theconnection between the upper portion of the inletor outlet-pipe and thenipple for producing an auxiliary connection with the nipple of theunion.

In testimony, that I claim the foregoing as my invention, I have signedmy name in presence of two subscribing witnesses.
